INVENTOR BROOK K. MOREHOUSE, OF GRAN Il JUNCTION, COLORADO;

- ROTARY rum.

designed for lifting water, the object of the 1g pum being to-lift at acomparatively low spee( a considerable uantity or weight of water, andafurther ject of the invention is a pump of the rotary type to whichwater will be supplied upon each side and disis charged from each side,thus balancing the pump. A

Thcinvention consists of the novel fea 'tures of constructionhereinafter full described, pointed out in the claims and s own in theaccompanying drawings, in which,

Figure 1 is a side elevation of the ump. --Fig. 2 is a section on theline 2'2 of ig. 1.

Fig. 3 is a horizontal section taken in the plane of ashaft. Fig. 4 is aside view of a wheel rovided with movable blades. Fig.

5 is a D etail sectional view showing a portion of aside of the pumcasing, and an end of one of the blades. ig. '6 "is a vertical sectiontaken'through the circumference of the pump casing. F1 7 is a detailview of a rim ortion; of the w eel showing one of the lades. Fi 8 is aside elevation showing a slightly m o ified form of wheel. 4 Fig. 9 is adetail sectioirthrough a portion of one side of the casing showiii insection an end portion of one of thebla es and illustrating certainmodifications in the construction of the cas-' ing and of the blade.'Fig. 10 is a detail pers ective view of an end portion of one of the 49ades illustrating the modification "shown in section'in 9.

-In these rawings A represents a casing formed in two halves whichare-bolted together, each half or section formingone side 4 of thecomplete casing. Each section carmesa central hub ortion A and. thesehub sections are parall to each other; One of the sections is providedupon its upper por tionjxith an outwardly estending projecting 50portion A and the other side or section is provided in its lowerportion-with a corresponding and oppositely extending projection A.

with res ect to-its lower portion and connected t ereto by curvedsidewalls, as is most clearly shown in Figs. 2 and 3.

Upon each side of the casing are secured supplemental casings B and B,these casings being 0 positely arranged upon opposite sides. of t .ecasing,,as indicated in Figs. 2 and 3. The supply ipe C is provided withtwo branches C and 2 which lead respectively to the casings B into whichthey discharge, the branch C dischar ing into the lower ortion of'itscasing B and the branch C disc arging swarms- 5m I downwardly into theupper portion of its casing B, audit will be understood that thesecasings B are upon opposite sides of the easing A and are also uponopposite sides of a central shaft to be hereafter described.

A discharge pipe D receives water from the casings B through branches Dand D, which also start from opposite sides of the casing A.

one side of the casin A and a1 alance w eel A disk F is keyed tohub'p'ortions A and this space is made water tight packing rings F setinto" the d sk F upon its opposite faces. That (portion of the diskbetween its periphery an the packing rings F is provided with radialslots prefer abl four in number and ninet degrees apart an these slotsare entirely fil ed by laterally movable blades G which work in them.The

blades G I stren then by forming longitudinally upon eac side of theblade a central rib G and I also groove the side and end edges of theblades and place in said grooves a suitable packing G The ends of theblades I refer to round or bevel asshown in Fi 5. also place strips ofpacking material upon the eripherly of the wheel F which strips extenfrom'b ado To admit water into and from the casing A I formcurved slotsJ in the side portions of the casing covered by the supplemental casingsB and B so that communication is afforded between theinterior of thecasing A165,

and these supplemental casings. I prefer to In the hub portions A isjournaledashaftEwhich carriesa' ulleyE' u on form the slots J in pairsleaving between the slots of each pair a web J In Figs. 8, 9 and 10 Ihave illustrated'some Z slight additions to the construction above F isrecessed u on its peripher 'as shown at H and the padlcing material I isa COIltlDu-l f described which are as follows :The wheel 1 through thepipe C and as sai %he eration of the device is as followgz- As the s aftE and wheel F are rotated the blades G by reasonof the slo ing of thesides of the casing A are moved ack and forth thro-u h'the slots of thewheel F. For example, w en a blade is at the extreme top of the casingit will be noon what may be termed the left-hand side (if the wheel F,and will ex- I tend parallel and entirely1 across the projecting. upperortion A of t e casing. lhis p o ,sitlon is ustrated in Fig. 2. When thewheel has made a one-fourth rotation clockthe blade will extend equallyupon each side of the wheel F. 'This o'sition of the bladeds shown inFig. 3 and ig. 7. When,

a one half rotation has been made the blade will have reached the limitof its travel to the right andgwill be in the" position occupied by thelower blade in Fig. 2, which iosition 1s,

%lso showy the blade when in e ovation in =1 I en th .ee-fourths of arevolution have been completed the blade will have traveled back towardthe left-hand side and is againtheposition, withrespect to the wheel Fshown m 3 and 7, and the blade will be moving in the direction of thearrow upon the left-hand blade of 3. At the same time 40 the bladediametrically 0 posits the blade whose c cle is being descri ed will bein the same re ative ositzon bpt will be moving in the opposite ction asindicatedby the arrow upon the righthand blade. 46

pleted the blade will have returned to the positionloccupied by theupper blade in Fig.2. The movement of the blades being thus understoodtheir action uponthe water admit- 50 ted to the pum [willbe readilyunderstood.

Water edmitte into the casing B upon the left-hand side of the casing Awill be caught as it passesthrough the slots J b an asoending blade andcarried over an above the shaft through the projectin portion A and beforced throu'"h the slots ll into. the casing B and into the ranch pipeD, the blade in the meantime passing over to the other side of thecasing. The water which had been carried around by said blade cannothowever,

pass through the wheel F and is therefore necessarily forced out throughthe casing B .I At the'ssme time'the blade opposite the.

one justreferred to is acting u on water fed 5 blade moves therevolution of the wheel F is com-' through said grooves andprojectingaltersec,4se p downwardly-it carries its supply of water under the shaftE through the portion A of the casingand forces it out through thecasing B upon the right-hand side of the pump and through the ipe D. Itwill be 0 vious'that each blade not only forces eitherover or' under theshaft as the case may be, the Water in advance of it, but also bysuction draws in an additional supply of water to be caught by thesucceeding blade. It will be obvious'thatas one blade asses through thewheel F and is relieved of its load-upon one-side by the followingblade, it takesup an additional load upon the 0posite side and in turnrelieves the preceding hide. The pump is therefore alwaysbalanced, theblades performin each an equal amount of 'worku on each side of thewheel F.. Havin thus in ly described my invention, what I claim as newand desire to secure by Letters Patent, is

1. A rotary ump comprising a .asin having hubport1ons, a shaft therein,a whee -u on said shaft, the said casing having paralle projectingportions upon opposite sides of said hub portion, blades carried by thewheel and movable through the wheel, said blades working in saidprojecting portions, su plemental casings carried by each side '9 thecasing first mentioned, the said first'fmentione casinghavingcommunication with the supplemental casings, a supply pipe hav ingbranches, one of said branches 0 euin into a supplemental casing up onone si e, an
